I don't think I've ever had to worry about existing VMs when upgrading
libvirt or virt-manager (BTW I think *libvirt* is more relevant to
this since that's what is actually managing the VMs).  I have upgraded
libvirt many times on my system that runs VMs even while the VMs were
running.

Since you've done the right thing by backing up the existing VMs and
*.xml files, you should be good even in the unlikely case that
anything goes wrong during the upgrade, so I guess go for it!
